Once again, on set and actually shooting, I don't seem to be able to set a page size over my shot to see what's going to be on the page and what isn't. Shooting 5D Mk IV to Mac Book Pro, tethered. Shooting interiors for a full page ad, so I need to be able to see the full page size and the full page bleed sizes over the image and see what's in-frame and what isn't. When I try to use the crop tool, I can't seem to change the area cropped into on the image without the crop becoming unconstrained. I need to keep that ratio constant. If I try to create a crop setting, it only allows full numbers, no decimal places. I don't really "get" the overlay tool. I want to see the image I'm shooting, not an overlay of something else, even a blank white file, over my image.

I'm assuming there's a video or instructions somewhere, but I can't find. Please help, very frustrated!

Hey Ben, unfortunately that only works with a ratio that is expressed with full numbers. Unfortunately, that's rarely the case. In this case I was shooting to page sizes:Live area: 7.875 x 10.375Bleed: 8.625 x 11.125and as it was an interior shoot, it quite critical where objects were in relation to the gutter and the 3 page edges.

The only videos I can find show using the Layout tool with a pre-set layout of text etc in a loose frame, but with no description of how to set an ACCURATE frame. It also forces me to go outside the program to create a mask, which seems counterintuitive for what's supposed to be a full featured program. As I say, there may well be a way to do this. Hoping maybe an experienced digi tech can jump in with advise?

Ah, so basically a larger PNG file, with a transparent area that matches the page size, and with the outside area set to a suitable dark opacity. OK. Makes sense. But I agree, with a product that is supposedly aimed at the pro's, it seems like an obvious tool feature to include. It's kind of ridiculous that I need to jump out of C1 to create that file in another program, import back in etc, and takes time out of my shoot when a client suddenly drops a new page size on me in the middle of a shoot. I shoot a lot without a dedicated DT on set, so I have to stop everything just to do that.
